To find the circumference of a circle, you can use the formula:
\[ C = 2\pi r \]
Where:
- \( C \) is the circumference,
- \( \pi \) is approximately 3.14,
- \( r \) is the radius.
Given that the radius \( r \) is 63:
\[ C = 2 \times 3.14 \times 63 \]
Now, calculate it step by step:
-
Multiply 2 by 3.14: \[ 2 \times 3.14 = 6.28 \]
-
Now multiply that result by 63: \[ 6.28 \times 63 = 395.64 \]
Therefore, the approximate circumference of the circle is 395.64 (rounded to the hundredths place).
